WILLIAM A. DOANE, OF SOUTH BREWER, MAINE.

WAVE-MOTOR.

Specification of Letters Patent.

Application filed April 23, 1914. Serial No. 835,025.

To all whom it may concern:

Be it known that I, WILLIAM A. DOANE, a citizen of the United States, residing at South Brewer, in the county of Penobscot and State of Maine, have invented new and useful Improvements in 'Wave Motors, of which the following is a specification.

The invention relates to a wave motor designed for utilizing the force of the waves for generating power, the apparatus being designed to utilize the elevating power of the waves from any direction.

The main object of the present invention is the provision of a wave motor utilizing a series of pivotally mounted levers to which is imparted a swinging movement under wave force, the levers operating through a series of air pumps to store compressed air for power purposes.

The invention in the preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a View in elevation of the improved wave motor. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal section on line 33 of Fig. 2. Fig. 4 is a horizontal section on line 41 of Fig. 2.

Referring particularly to the accompanying drawings, the improved wave motor comprises a float 1 from which rises a central standard 2 supporting at its upper end a bed plate 3. The bed plate is of less diameter than that of the float and is further supported from the latter through the medium of braces 4. Rising from the bed plate is a cylindrical housing 5 preferably of sheet iron or the like, within which is mounted the operating mechanism, the housing hav ing diagonal braces 6 extending to the float.

Centrally supported on the bed plate 8 is a casting 7 in which are arranged diametrically opposed pairs of cylinders 8 and a central vertically extending chamber 9. each cylinder being connected with the chamber through a conduit 10; Cylinders and chamber are preferably cored from the solid cast ing to provide the desired solidity of structure. Secured upon the upper end of the casting 7 are fulcrum bars 11, said bars extending beyond the edge of the casting. there being one bar for each cylinder 8, with the bar arranged directly above the cylinder. Pivotally mounted in each fulcrum bar is provided with a whistle 19.

a weight lever 12, the pivot 13 of the lever permitting swinging movement of said lever on the bar. The lower end of the weight lever is connected at let to the piston rod 15 operating in the cylinder 8, being connected to the piston 16 therein, whereby the swinging movement of the lever actuates the piston. Curved guides 17 are arranged in pairs for each weightlever, guiding said lever in movement, as will be evident. The outer ends of the guides are connected to the wall of the housing and their inner ends to the wall of the chamber 9 and the storage cylinder 18 is secured to and is in open communication with the chamber 9, the upper end of the cylinder 18 projecting through the top of the housing and being preferably The upper ends of the levers 12 are provided with weights 20, which may be of any desired size. Secured to the storage cylinder 18 is a cage 21 within which for each weight lever is arranged an impact bell 22, a similar but larger bell 23 being secured within a cage 24 on the outer side of the housing, there Patented Mar. 28, 1916. p

being thus provided a pair of bells for each weight lever adapted to be sounded by said lever at its limit of movement in each direction. Posts 25 extend from the casting 7 and from the housing with their upper ends approximately at the limit of movement of each lever, each post being provided with a head 26 carrying a bowed spring 27 on the impact face, the springs acting as a bumper spring for the lever in its movement.

In the adaptation of the wave motor illustrated, I have shown it as adapted as a warning buoy, and under these circumstances I prefer to provide within the housing 5 at onev side of the storage cylinder 18 a casing 28 within which is arranged a generator 29 in circuit with the light 30 supported in a housing 31 on the upper portion of the housing 5.

The whistle 19 and generator 29 are onerated through any appropriate or wellrnown control by means of the compressed air in the storage cylinder 18.

The wave motor is anchored at an appro-' priate point so that the float is tilted from one side to the other under the force of the waves and durin this tilting operation. the levers assisted by their weighted ends are swung back and fo th operating the pistons and storing compressed air in the tank 18.

If desired, the levers may be provided with friction rolls 32 for cooperation with the guide.

While the motor is shown and designed as a Warning buoy, it is obvious that the principle employed may be utilized for the gen eration of power for any purpose, and. hence no limitation is intended herein by the specific illustration of the utilization of such power. This motor may also be used for pumping water, if sodesired.

' What is claimed is 2- 1. A wave motor comprising a fioat, a housing supported thereby, a series of pumps arranged horizontally Within the housing and disposed at approximate right angles to each other, levers pivotally supported by and disposed remotely fromvthe respective pumps, oneend of each of the levers having connection with the adjacent pump, a storage chamber arranged within'the casing and above and in open communication with the pumps, guides projecting from said chamber to the casing, means carried by each le-- ver cooperating with one of the guides, and similar means carried by the casing and by the pumps to limit movement of the levers supported by the pumps, said tank being in. open communication w1th the pumps, curved guides extending from the storage tank to the casing, bars projecting from each pump,-

a lever supported in each of said bars, one end of the lever being operatively connected to the pump, said lever intermediate its ends being provided with anti-friction means to I cooperate with one of the guides,and buffers carried respectively by (the pumps and by the casing to receive and limit the operative movement of the levers.-.

In testimony whereof I afiix my signature;

in presence of two Witnesses.
